[0041] E1: Diaminopolyethylene glycol modified hyperbranched polypyrrone, prepared by the following method:
[0042] (1) Preparation of naphthalene anhydride-capped hyperbranched polypyrrole solution
[0043] Add 1 mole of 1,3,5-tris(4-naphthyloxy-1,8-dioic acid) trimellitic anhydride and 2000ml m-cresol in a completely dry three-necked flask, stir under nitrogen protection, when the trianhydride After completely dissolving, add 0.5 mole of 3,3'-diaminobenzidine, stir at room temperature for 30 minutes, heat to 85°C, react for 3.5h, then react at 185°C for 4.5h; after the reaction, drop to At room temperature, naphthalene anhydride-capped hyperbranched polypyrrole solution is obtained;
[0044] (2) Preparation of diaminopolyethylene glycol modified hyperbranched polypyrrone
[0045] To the naphthalene anhydride-capped hyperbranched polypyrrole solution obtained in step (2), add 2 moles of diaminopolyethylene glycol with an average degree of polymerization of 226, stir at roo...
